IMPROVEMENT IN SPARK-ARRESTERS.

Specification forming part of Letters Patent No. 168,091, datedSeptember 28, 1875; application filed June 28, 1875.

j To all whom it may concern:

Be it known thatl, WILLIAM HALsCrED, of Trenton, New Jersey, haveinvented a i Spark-Arrester, of which the following is a right orvertical position, I place the smokepipe or smoke-stack in a horizontalposition,

projecting it forward over the cow-catcher, covering the iiues of theboiler, so Vthat the smoke of the iiues may pass in a straight line intothe smoke-pipe or smoke-stack, as appears in Figure 3,letter A. Theexhaust-pipes for the steam, which are represented in Fig. 2, letters VBB, have their ends turned so as to project the steam in a straight lineinto the end or opening of the smoke-stack which covers the iiues of theboiler. The front end of the smoke-pipe or smoke-stack is turneddownward, so as to enter and be fitted closely into a triangular box orcovering of the cowcatcher, made of sheet iron or copper, or othermetal, and fastened in a proper manner on the outer rim of thecow-catcher, so as to be air-tight on the top and sides, as representedin.Fig. 3, letters D B. The sides of this box are perpendicular and thetop of it flat, and it may be from two and a half to four feet or morein height, according to the size of the engine for which it is to beused. The top of it should he made, as it were, double, so that it mayform a water-tight compartment or tank of a depth of about four inchesor more/ under the whole surface of the upper lcovering of thetriangular box. The under side of this compartment or tank, for thespace of a number of inches, say, six, eight, or more inches around thehole where the forward end of the smoke-pipe or smoke-stack projectsinto this triangular box, which covers the cowcatcher, is perforated toallow the water to drip through the same, and fall onto the road orcow-catcher, or corrugated plate of sheetiron attached to the front partof the cowcatcher. The corrugated plate above mentioned is representedin Fig. 4, letters A" All', and the triangular box or covering of thecowcatcher is represented in Fig. 3. lIhe little elbow or pipe on thetop of the covering of the triangular box (represented by letter G inFig. 3) represents the pipe by which water may be conveyed into the tankor water-tight compartment made in the top of the triangular box orcovering aforesaid.

'Ihe cow-catcher may be made in any ordinary form. The only alterationor addition which I make for the purpose of my inven- 'tion is theplacing of a corrugated plate of sheet-iron or other met-al, extendingfrom the front point thereof backward and downward 4to the distance oftwo or three feet, as represented in Fig. 4, letters A Af, so that thewater that drips from the water-tight compartment may fall upon the saidplate of sheetiron and keep it constantly' wet, and that the sparks fromthe front end of the smoke-pipe may also fall thereon and beextinguished by the Water thereon, or which may drip upon f them whilethere, and may from thence fall upon the railroad-track.

Another good effect which may be produced by allowing the water to dripdown upon the cow-catcher, in the manner aforesaid, will be to cool thesmoke, so as to reduce its temperature to a degree not higher than thatof the atmosphere, and therefore to prevent its rising so high or sofast as to annoy -persons in the car.

What I claim as my invention is l. In combination with a locomotive, asmoke-stack or chimney projecting -from the engine directly forwardhorizontally over the cow-catcher, and. having its foremost end turneddownward, and entering a box which covers the cow-catcher, substantiallyas and for the purpose set forth.

2. In combination with a smoke-stack or chimney projecting horizontallyfrom the locomotive, a triangular box or covering over the cow-catcher,the combination serving to convey the. sparks and igneous matterdirectly forward from the smoke-stack, and then down upon the trackforward of the locomotive.

3. lIn combination with the box which covers the cow-catcher, a tank orwater-compartment located in the top of such box, and provided withperforations or Water-outlets in its Vbottom7 to permit the Water todrip through the same, substantially as and for the purpose set forth.

4. In combination with the box that covers the cow-catcher, and with aWater-dripping apparatus, the corrugated or grooved plate beneath thecow-catcher, and inclining backward, and serving t0 receive the fallingWater and the cinders or sparks, and to extinguish them, allsubstantially as set forth.
